exposed area to dene Shinglesiinulatingtabs. 'lhese strips, as is well known, are laid up on the roof in successive overlapping courses with the adjacent strips of each 5 course arranged side by side and with the overlapping strips of each course in staggered relation with respect to the strips of the preceding course. When shingles ci? this type are thus arranged on a root, the slots or notches necessarily expose a corresponding area of the normal concealed or overlapped portions oi" the underlying strip, and water seeping or blowing in under the strips, especially near the upper ends oi' the slots, is very liable to reach the roof supporting structure unless the strips are sutciently wide to underlap the shingles ot the su@ ceeding course tor a considerable distance be-1 yond the upper ends of the slots therein.

'lhe principal object oit my invention re sides in the 'iormation oi shingle strips in such a manner that the tab-defining slots thereof as well as the joints between adjacent strips in a course, are sealed or closed i cti so as to avoid the possibility ot water gaining entrance beneath the upper ends oi the slots,` or through the joints.

further object of the invention is to provide the strips with closure elements for the tab-deiining slots secured to the underiace of the strips, in such relation tc the tabdetining slots as to realize the principal object of the invention as aforesaid.

W'ith the above and other objects in view, which will appear as the description proceeds, my invention consists in the novel construction, arrangement and combination of various elements and parts described in the following specification and illustrated in the accompanying drawing. lVhile l. have ilreas.

lustrated and will describe certain preferred embodiments of the invention, it will be understood that such variations or medications thereof may be made as will tall with- '55 in the scope ci the appended claims.

ln the drawing,

Figure l is a plan view ot one forni ci? my improved shingle strip,

Figure 2 is an edge view thereof,

Figli modified construction.

rlfhe strips, according to my invention, are formed of eaible water-resistant ibrous base, such as the ordinary asphaltic telt-ibase re 3 is a plan view showing a slightly a@ rooting fabricated from sheets of rag, as- 65 bestos or similar bers. These sheets are rendered water-resistant by impregnating them with asphalt or the like, and one or both surfaces thereof are then supplied with Va'coatas blown asphalt having a melting point approximately 2200 F. Mineral surfacing such as crushed slate is partially imbedded in the coating layer on the surface to be exposed on the root, and when the opposite surface of the sheet also has a coating layer, the latter is generally provided with a surfacing ot line mineral such as talc or mica.

,ds shown, the shingle strip is indicated generally by the numeral l0 and comprises an upper portion il which is the uneaposed or concealed part ot the strip when laid, and a loweror weather exposed area 12. The exposed portion lQ is formed with shingle ing layer of weather resistant material such 'm simulating tabs i3 defined from each other 85 by spaced vertical intermediate slots ld. and terminal notches ila, which are preferably made in the sheet at an appropriate staffe or its fabrication prior to the severance ci? the strips l() from the sheet. The tab-denng 9 slots or. notches lil, ida, may be spaced apart at equal distances so as to provide shingle simulating tabs oi equal width, or they may be spaced apart at variable distances as shown, so as to torni tabs of varying widths. 95

form closures for the tab-defining slots or notches. Y l

In the form shown in Figure 1, bands or strips 16, of a length corresponding to the hei ht of the shingle strip and of a width su cient to extend beyond'tlre side edges'of slots 14, are secured to the bottom face of the strip 10 in position to underlie the slots 14. At one end of the strip, I secure a somewhat widerband17, to the underface of the strip, leaving a portion of the nband 17 Y projecting beyond the side edge of the shingle stri 10. The strips 16 and i7 may be affixed to t e shingle strips by any suitable adhesive such as molten asphalt, or aqueous dispcr= sion ofasphalt or the like Figure 3, the construction isV modified only to the extent that the closure bands or strips 16a, 17a, corres onding to the strips i6-, 17, respective ly, of igures lfand 2, are made shorter, and extend only from the buttedge of the shinglestrips to a point sliglitiyabore the upper ind of the tab-deliningslots ifi, 14a, instead of extending all the way to tbe upper edge of the shingle strip. y

The shingle strips may 4ne *fici on the roof in the customary fashion, with the projecting ortions of the Ytermi-nal bands 17 or 17a apped by the opposite and of an adJoining shingle. When two adjoiningshingle strips are thus laid together side by side, the notches 14a at the'oppose'd ends of the strips 'coniplete the appearance of tao-dening slots at the ends of the strips, 'rfiiiie the bands or strips 17, 17a, ei'ectivelj,T seni the same inthe manner described. Y If desir ed, adhesive material may be a plied te the lapped portions of the end ban s to aid i 'f L to the underface of the c strip, but in any event, th the shingle strips are same at points slightly c of the slots so as to pass tL strips.

As a further feature of the invention, the upper surface of the sealing or closure bands may be left unsurfaced they may carry partially embedded crushed minerai grit of dark color in comparison to the color of the mineral grit affixed te the exposed face of the shingle strip, thus gre "ff accentuating the individual shingle-sini Wting effect of the slots. Furthermore, ien the strips are applied on the roof, warf may collect in the channel formed by tab-defining slots and the underlying cA sure strip will pass downwardly under the i' lluence of the natural pitch of the roof and Grain onto the surface ofthe sub-adjacent stripa Accordingly, instead of the lusual construction wherein water may creep or be blown up under the shingles through the tab-definiinY slots, I provide by inv i a construe tion in which a' definite nath forms a ,c ie upper ends iroegh the sealing ositive drain for water reaching and col eating in the slots.

The sealing strips willgpreferably be of less thickness than the shingle strip itself so as not to elevate the exposed portion of the shingles materially above the surface of the underlying shingles in the preceding courseI Shingle strips constructed in accordance with my invention also afford certain advanL tages when subjected to a recoating and resurfacing operation of the type set forth in the Patent Number 1 612,776 to Lester Kirhbraun. In accordance with the said patent shingles or shingle strips are subjected to reiinmersion in asphaltic coating material in order to encase the weather exposed surfaces and edges of the shingle elements in a protecting layer of weatherproof material, the recoated areas being also referably surfaced with crushed mineral ci) a suitable variety. In the practical manufacture of strips in accordance with the saidKirschbraun patent, the treatment provided by said patent is generally reserved for shingle seconds, that is to say, shingles as ordinarily produced but which carr slight imperfections or irregularities which do not perceptibly affect the life of the shingle and which are objectionable only from the viewpoint of appearance. The recoating and resurfacing operation accordingly provides an effective means for re claiming shingle seconds and converting them into a more desirable type of shingle, this being advantageous also from the standpoints that the exposed surfaces and edges are sealed against the action of the elements, and further that the recoated and resurfaced elements present an increased thickness of highl; desirable texture along the butt edges t ereof.

In thus reclaiming shingle seconds, it frequently happens that the shingle to be retreated is of a light color and the mineral surfacin usedin the retreating operaiton is of a dar color. In these cases, therefore, when the retreated shingles are laid upon the roof, the light color of the upper portion of the shin les, (the retreating operation not being app iedto these portions), is visible through the slots of the overlying shingles and this is frequently objectionable and heretofore has been overcome only by a careful and tedious selection of the color of the shingies to be retreated in accordance with the color of the mineral to be used in the retreating operation. In the shingle strips as provi ed by my invention, on the other hand, the sealing strips conceal the mineral surfacing on the upper portions of the underlying strip, and hence shingles constructed in accordance with my invention, may be retreated in acn cordance with the said Kii'sciibraun patent Without reference to their original color.

The shingle strip construction of my iiivention also affords certain advantages in connection with the production of shingles, the exposed areas whereof are formed with a layer of copper by electrodeposition. In the actualpractice of electrodeposiiing copper on mineral surfaced prepared roofing shingles,the deposition of copper is confined substantially to the areas to be exposed, as otherwise the cost would be prohibitive. In electrodepositing copper upon shingles of the square butt variety, it is necessary to deposit the copper not only upon the lower portions of the shingles which form the Weather-exposed areas thereof, bu-t also to form an electrodeposited tongue of copper on the upper portions of the shingle intermediate the tab-defining slots, so that when the shingles are applied in courses on the roof,v

these tongues of copper will underlie the slots and be visible therethrough. The electrodeposition of these separate tongues extending into the upper areas of the shingles, involves a rather sensitive operation in commercial practice and represents a costly element of the manufacture. The necessity for thus plating the tongues of copper may be avoided with shingles constructed in accordance with my invention, for, as will be noted, when the lower or weather-exposed areas of my strip shingle are made electroconductive, and then passed through an electroplating bath, the copper will be deposited not only upon the surface of the tabs 13, but also upon the surface of the sealing strips exposed through the slots 14, 14a, so that when these electroplated copper shingles are applied on the roof, the entire visible exposed surface will carry the copper coating and hence there is no necessity for plating tongues of copper in the upper areas of the shingle as heretofore.

If desired, in some instances, the tab-defining slots 14 may be formed at an inclination to the vertical, instead of perpendicularly to the butt-edges of the strips.

Having thus described my invention, it will be understood that numerous changes and modifications may be made therein without departing from the spirit of the invention as dened in the subjoined claims.

I claim as my invention:

1. A roofing element comprising a body portion and spaced sealing strips secured to the underface of the body portion, the body portion being formed with tab-defining slots in the weather-exposed areas thereof, said slots cut therethrough being confined to portions of the weather-exposed areas which are underlaid by said sealing strips.

2. A shingle strip comprising a body portion formed with spaced slots cut through the exposed areas thereof, spaced sealing strips adhering to the undersurface of said strip directly beneath said slots and a sealing strip adhering to the undersurface of said strip near one of its lateral edges and extending a substantial distance beyond said ed e.

2. As an article of manufacture, a shingle strip having spaced slots out through the lower portion thereof to form a plurality of tabs, spaced sealing strips of less thickness t-han the shingle strip fastened to the lower face of said strip under each slot and a sealing strip fastened to the undersurface of said shingle strip near one of the lateral edges thereof so as to extend a substantial distance beyond said lateral edge.
